Accounting Policies [Abstract]
Business Overview and Summary of Significant Accounting Policies	Business Overview and Summary of Significant Accounting Policies: Overview Description of Business. Science Applications International Corporation (collectively, with its consolidated subsidiaries, the “Company”) is a leading provider of technical, engineering and enterprise information technology (IT) services primarily to the U.S. government. The Company provides engineering and integration services for large, complex projects and offers a broad range of services with a targeted emphasis on higher-end, differentiated technology services. The Company is organized as a matrix comprised of three customer facing operating segments supported by a strategy, growth and innovation organization. Each of the Company’s three customer facing operating segments is focused on providing the Company’s comprehensive technical, engineering and enterprise IT service offerings to one or more agencies of the U.S federal government. The Company's operating segments are aggregated into one reportable segment for financial reporting purposes, see Note 16. Acquisitions. On March 13, 2020, the Company completed the acquisition of Unisys Federal, a former operating unit of Unisys Corporation, which enhances our capabilities in government priority areas, expands our portfolio of intellectual property and technology-driven offerings, and increases our access to current and new customers. On January 14, 2019, the Company completed the acquisition of Engility Holdings, Inc. (collectively with its consolidated subsidiaries, "Engility"), which provides increased customer and market access, as well as increased scale in strategic business areas of national interest, such as defense, federal civilian agencies, intelligence and space. Principles of Consolidation and Basis of Presentation References to “financial statements” refer to the consolidated financial statements of the Company, which include the statements of income and comprehensive income, balance sheets, statements of equity and statements of cash flows. These financial statements were prepared in accordance with U.S. generally accepted accounting principles (GAAP). All intercompany transactions and account balances within the Company have been eliminated. Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. Non-controlling Interest. The Company holds a 50.1% majority interest in Forfeiture Support Associates J.V. (FSA). The results of operations of FSA are included in the Company's consolidated statements of income and comprehensive income. The non-controlling interest reported on the consolidated balance sheets represents the portion of FSA’s equity that is attributable to the non-controlling interest. Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Significant estimates inherent in the preparation of the financial statements may include, but are not limited to estimated profitability of long-term contracts, income taxes, fair value measurements, fair value of goodwill and other intangible assets, pension and defined benefit plan obligations, and contingencies. Estimates have been prepared by management on the basis of the most current and best available information at the time of estimation and actual results could differ from those estimates. Reporting Periods The Company utilizes a 52/53 week fiscal year ending on the Friday closest to January 31, with fiscal quarters typically consisting of 13 weeks. Fiscal 2019 began on February 3, 2018 and ended on February 1, 2019, fiscal 2020 began on February 2, 2019 and ended on January 31, 2020, and fiscal 2021 began on February 1, 2020 and ended on January 29, 2021. Stock-based Compensation The Company issues stock-based awards as compensation to employees and directors. Stock-based awards include stock options, vesting stock awards and performance share awards. These awards are accounted for as equity awards. The Company recognizes stock-based compensation expense net of estimated forfeitures on a straight-line basis over the underlying award’s requisite service period, as measured using the award’s grant date fair value. For performance share awards, the Company reassesses the probability of achieving the performance conditions at each reporting period end and adjusts compensation expense based on the number of shares the Company expects to ultimately issue. Income Taxes The Company accounts for income taxes under the asset and liability method of accounting, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Under this method, changes in tax rates and laws are recognized in income in the period such changes are enacted. The provision for federal, state, local and foreign income taxes is calculated on income before income taxes based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provision differs from the amounts currently payable because certain items of income and expense are recognized in different reporting periods for financial reporting purposes than for income tax purposes. Recording the provision for income taxes requires management to make significant judgments and estimates for matters for which the ultimate resolution may not become known until the final resolution of an examination by taxing authorities or the statute of limitations lapses. Additionally, recording liabilities for uncertainty in income taxes involves significant judgment in evaluating the Company’s tax positions and developing the best estimate of the taxes ultimately expected to be paid. Tax penalties and interest are included in income tax expense. The Company records net deferred tax assets to the extent these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent results of operations. If it is determined that the Company would be able to realize the deferred income tax assets in the future in excess of their net recorded amount or would no longer be able to realize the deferred income tax assets in the future as currently recorded, an adjustment would be made to the valuation allowance, which would decrease or increase the provision for income taxes. The Company has also recognized liabilities for uncertainty in income taxes when it is more likely than not that a tax position will not be sustained on examination and settlement with various taxing authorities. Liabilities for uncertainty in income taxes are measured based on the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Deferred tax assets and liabilities are netted by taxable jurisdiction and classified as noncurrent on the consolidated balance sheets. Costs Allocated to Contracts The Company classifies indirect costs as overhead (included in cost of revenues) or general and administrative expenses in the same manner as such costs are defined in the Company’s Disclosure Statements under U.S. government Cost Accounting Standards (CAS). Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents are comprised of cash in banks and highly liquid instruments, which primarily consist of bank deposits and investments in institutional money market funds. The Company includes outstanding payments within cash and cash equivalents and accounts payable on the consolidated balance sheets and as of January 29, 2021 and January 31, 2020 these amounts were $25 million and $54 million, respectively. The Company does not invest in high yield or high risk securities. The cash in bank accounts at times may exceed federally insured limits. Restricted cash consists of cash on deposit in rabbi trusts that are contractually restricted from use in operations, but are subject to future claims of creditors. Restricted cash will be used primarily to fund future payment obligations related to deferred compensation plans and our voluntary disability insurance plan in California. The following table provides a reconciliation of cash, cash equivalents and restricted cash to amounts reported within the consolidated balance sheets for the periods presented: January 29, 2021 January 31, 2020 (in millions) Cash and cash equivalents $ 171 $ 188 Restricted cash included in other current assets 5 4 Restricted cash included in other assets 14 10 Cash, cash equivalents and restricted cash $ 190 $ 202 Receivables Receivables include billed and billable receivables, and unbilled receivables. The Company’s receivables are primarily due from the U.S. government, or from prime contractors on which we are subcontractors and the end customer is the U.S. government, and are generally considered collectable from the perspective of the customer’s ability to pay. The Company does not have a material credit risk exposure. Unbilled receivables, substantially all of which are expected to be billed and collected within one year, are stated at their estimated realizable value and consist of costs and fees billable on contract completion or the occurrence of a specified event, other than the passage of time. Legal title to the related accumulated costs of contracts in progress generally vests with the U.S. government on the Company’s receipt of progress payments. Progress payments received of $28 million and $33 million offset unbilled receivables as of January 29, 2021 and January 31, 2020, respectively. Contract retentions are billed when contract conditions have been met and may relate to uncompleted indirect cost negotiations with the U.S. government. Based on historical experience, the majority of retention balances are expected to be collected beyond one year. Retention is presented in other assets on the consolidated balance sheets, see Note 3. Write-offs of retention balances have not been significant. Receivable balances are written-off in the period during which management determines they are uncollectable, and, at that time, such balances are removed from billed receivables and, if previously reserved, from the allowance. Inventory Inventory is substantially comprised of finished goods inventory purchased for resale to customers, such as tires and lubricants, and is valued at the lower of cost or net realizable value, generally using the average method. The Company evaluates current inventory against historical and planned usage to estimate the appropriate provision for obsolete inventory. The Company recognized a $26 million provision for inventory within cost of revenues during fiscal 2019 related to firm purchase commitments on a firm-fixed price program. Business Combinations The Company records all tangible and intangible assets acquired and liabilities assumed in a business combination at fair value as of the acquisition date, which is determined using a cost, market or income approach. The excess amount of the aggregated purchase consideration paid over the fair value of the net of assets acquired and liabilities assumed is recorded as goodwill. Acquisition date fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as measured on the acquisition date. The valuations are based on information that existed as of the acquisition date. During the measurement period that shall not exceed one year from the acquisition date, the Company may adjust provisional amounts recorded for assets acquired and liabilities assumed to reflect new information that the Company has subsequently obtained regarding facts and circumstances that existed as of the acquisition date. Acquisition and Integration Costs Acquisition-related costs that are not part of the purchase price consideration are generally expensed as incurred, except for certain costs that are deferred in connection with the issuance of debt. These costs typically include transaction-related costs, such as finder’s fees, legal, accounting and other professional costs. Integration-related costs typically include strategic consulting services, employee related costs, such as severance and accelerated vesting of assumed stock awards, costs to integrate information technology infrastructure, enterprise planning systems, processes, and other non-recurring integration-related costs. Acquisition and integration costs are presented together as acquisition and integration costs on the consolidated statements of income. The amounts recognized in acquisition and integration costs on the consolidated statements of income are as follows: Year Ended January 29, January 31, February 1, (in millions) Acquisition (1) $ 20 $ 2 $ 31 Integration (2)(3) 34 46 55 Total acquisition and integration costs $ 54 $ 48 $ 86 (1) Acquisition expenses recognized for the twelve months ended January 29, 2021, and January 31, 2020 are related to the acquisition of Unisys Federal. Acquisition expenses recognized for the twelve months ended February 1, 2019 are related to the acquisition of Engility. See Note 4 for additional information related to the acquisitions. (2) Integration expenses for the twelve months ended January 29, 2021, include an $11 million loss associated with the divestiture of non-strategic international operations. (3) Includes $6 million, $16 million, and $29 million of restructuring costs for the year ended January 29, 2021, January 31, 2020, and February 1, 2019, respectively, and $1 million and $5 million of impairment of right of use lease assets for fiscal 2021 and fiscal 2020, respectively. See Note 5 for additional information related to restructuring costs and impairments. Divestiture On July 3, 2020, in connection with the integration of Engility, the Company sold certain non-strategic international operations for $22 million and recognized a loss on the divestiture of $11 million, including $1 million of transaction costs. The loss is included in acquisition and integration costs on the consolidated statements of income. The Company has received $17 million in cash proceeds through January 29, 2021, with the remaining balance due in installments through October 2021. Goodwill and Intangible Assets Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired and liabilities assumed. Goodwill and indefinite-lived intangible assets are not amortized, but rather are tested for potential impairment annually at the beginning of the fourth quarter, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. There were no impairments during the periods presented. The goodwill impairment test is performed at the reporting unit level. The Company estimates and compares the fair value of each reporting unit to its respective carrying value including goodwill. The fair value of the Company’s reporting units are determined using either a market approach, income approach, or a combination of both, which involves the use of estimates and assumptions, including projected future operating results and cash flows, the cost of capital, and financial measures derived from observable market data of comparable public companies. If the fair value is less than the carrying value, the amount of impairment expense is equal to the difference between the reporting unit’s fair value and the reporting unit’s carrying value. Intangible assets with finite lives are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives. Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment of Long-lived Assets The Company evaluates its long-lived assets for potential impairment whenever there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable and the carrying amount of the asset exceeds its estimated future undiscounted cash flows. When the carrying amount of the asset exceeds its estimated future undiscounted cash flows, an impairment loss is recognized to reduce the asset’s carrying amount to its estimated fair value based on the present value of its estimated future cash flows. Commitments and Contingencies Accruals for commitments and loss contingencies are recorded when it is both probable that they will occur and the amounts can be reasonably estimated. In addition, legal fees are accrued for cases where a loss is probable and the related fees can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount of loss. The Company reviews these accruals quarterly and adjusts the accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other updated information. Pension and Defined Benefit Plans The Company measures plan assets and benefit obligations as of the month-end that is closest to its fiscal year-end. Accounting and reporting for the Company's pension and defined benefit plans requires the use of assumptions, including but not limited to, a discount rate and an expected return on assets. These assumptions are reviewed at least annually based on reviews of current plan information and consultation with the Company's independent actuary and the plans’ investment advisor. If these assumptions differ materially from actual results, the Company's obligations under the pension and defined benefit plans could also differ materially, potentially requiring the Company to record an additional liability. The Company's pension and defined benefit plan liabilities are developed from actuarial valuations, which are performed each year. Marketable Securities Investments in marketable securities consist of equity securities, which are recorded at fair value using observable inputs such as quoted prices in active markets (Level 1). As of January 29, 2021 and January 31, 2020, the fair value of our investments total $27 million and was included in other assets on the consolidated balance sheets. The Company's investments are primarily held in a custodial account, which includes investments to fund our deferred compensation plan liabilities. Fair Value Measurements The Company utilizes fair value measurement guidance prescribed by GAAP to value its financial instruments. The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than the quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). The carrying amounts of cash and cash equivalents, receivables, accounts payable and other amounts included in other current assets and current liabilities that meet the definition of a financial instrument approximate fair value because of the short-term nature of these amounts. The carrying value of the Company’s outstanding debt obligations approximates its fair value. The fair value of long-term debt is calculated using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements. Non-financial assets acquired and liabilities assumed in a business combination were measured at fair value using income, market and cost valuation methodologies. See Note 4. The fair value measurements were estimated using significant inputs that are not observable in the market and thus represent a Level 3 measurement. Derivative Instruments Designated as Cash Flow Hedges Derivative instruments are recorded on the consolidated balance sheets at fair value. Unrealized gains and losses on derivatives designated as cash flow hedges are reported in other comprehensive income (loss) and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions. The Company’s fixed interest rate swaps are considered over-the-counter derivatives, and fair value is calculated using a standard pricing model for interest rate swaps with contractual terms for maturities, amortization and interest rates. Level 2, or market observable inputs (such as yield and credit curves), are used within the standard pricing models in order to determine fair value. The fair value is an estimate of the amount that the Company would pay or receive as of a measurement date if the agreements were transferred to a third party or canceled. See Note 12 for further discussion on the Company’s derivative instruments designated as cash flow hedges. Operating Cycle The Company’s operating cycle may be greater than one year and is measured by the average time intervening between the inception and the completion of contracts. Research and Development The Company conducts research and development activities under customer-funded contracts and with company-funded independent research and development (IR&D) funds. IR&D efforts consist of projects involving basic research, applied research, development, and systems and other concept formulation studies. Company-funded IR&D expense is included in selling, general and administrative expenses (SG&A) and was $6 million, $7 million and $5 million in fiscal 2021, 2020 and 2019, respectively. Customer-funded research and development activities performed under customer contracts are charged directly to cost of revenues for those particular contracts. Accounting Standards Updates In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which requires entities to use a forward-looking model to estimate credit losses over the contractual term of financial assets, including short-term trade receivables and contract assets. The Company adopted ASU 2016-13 in the first quarter of fiscal 2021 using the modified retrospective approach. The adoption did not have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which aligns the capitalization requirements for implementation costs incurred in a hosting arrangement that is a service contract with the existing capitalization requirements for implementation costs incurred to develop or obtain internal-use software ( Subtopic 350-40 ). During the third quarter of fiscal 2020, the Company early adopted ASU 2018-15 and applied its provisions prospectively. The adoption did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases ( Topic 842 ), which supersedes the existing lease accounting standards ( Topic 840 ). The Company adopted the standard using the optional transition method. Accordingly, the prior periods were not recast, and all prior period amounts disclosed are presented under Accounting Standards Codification (ASC 840). As a result of the adoption of the new standard, on February 2, 2019, the Company recognized approximately $169 million of right of use operating assets and $184 million of operating lease liabilities, of which $140 million was noncurrent. The adoption did not have a material impact on retained earnings, the consolidated statements of income, or the consolidated statements of cash flows. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans , which modifies the disclosure requirements for the defined benefit pension plans and other postretirement plans. The Company early adopted the provisions of the standard in the fourth quarter of fiscal 2019, which did not result in a material impact to its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the revenue recognition requirements and some cost guidance included in the ASC. The Company adopted the standard on February 3, 2018, using the modified retrospective method. Under this method, the Company recognized the cumulative effect of adoption as an adjustment to its opening balance of retained earnings on February 3, 2018. Prior year periods were not retrospectively adjusted. The net impact to opening retained earnings as a result of the adoption was $3 million, attributable primarily to the change in accounting for programs previously accounted for using the efforts-expended method of percentage of completion. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedge Activities , which simplifies the application of hedge accounting and eliminates the requirement to separately measure and report hedge ineffectiveness. The Company early adopted the provisions of the standard in the first quarter of fiscal 2019. The adoption did not have a material impact on the Company's financial statements. Other Accounting Standards Updates effective after January 29, 2021 are not expected to have a material effect on the Company’s financial statements.

Earnings Per Share [Abstract]
Earnings Per Share, Share Repurchases and Dividends	Earnings Per Share, Share Repurchases and Dividends: Earnings per Share (EPS) Basic EPS is computed by dividing net income attributable to common stockholders by the basic weighted-average number of shares outstanding. Diluted EPS is computed similarly to basic EPS, except the weighted-average number of shares outstanding is increased to include the dilutive effect of outstanding stock options and other stock-based awards. A reconciliation of the weighted-average number of shares outstanding used to compute basic and diluted EPS was: Year Ended January 29, January 31, February 1, (in millions) Basic weighted-average number of shares outstanding 58.1 58.4 43.4 Dilutive common share equivalents - stock options and other stock-based awards 0.6 0.6 0.7 Diluted weighted-average number of shares outstanding 58.7 59.0 44.1 The following stock-based awards were excluded from the weighted-average number of shares outstanding used to compute diluted EPS: Year Ended January 29, January 31, February 1, (in millions) Antidilutive stock options excluded 0.3 0.3 0.2 Share Repurchases The Company may repurchase shares in accordance with established repurchase plans. The Company retires its common stock upon repurchase with the excess over par value allocated to additional paid-in capital. The Company has not made any material purchases of common stock other than in connection with established share repurchase plans. On March 27, 2019, the number of shares of our common stock that may be repurchased under our existing repurchase plan, previously announced in October 2013, was increased by approximately 4.6 million shares, bringing the total authorized shares to be repurchased under the plan to approximately 16.4 million shares. As of January 29, 2021, the Company has repurchased approximately 12.0 million shares of common stock under the plan. Dividends The Company declared and paid quarterly dividends every quarter for the years presented, increasing from $0.31 to $0.37 per share in the first quarter of fiscal 2020. Total dividends declared and paid were $1.48 per share during fiscal 2021 and fiscal 2020 and $1.24 per share during fiscal 2019. Subsequent to the end of fiscal 2021, on March 23, 2021, the Company’s Board of Directors declared a cash dividend of $0.37 per share of the Company’s common stock payable on April 30, 2021 to stockholders of record on April 16, 2021.

Revenue from Contract with Customer [Abstract]
Revenues	Revenues: Revenue Recognition The Company provides technical, engineering and enterprise IT services under long-term service arrangements primarily with the U.S. government including subcontracts with other contractors engaged in work for the U.S. government. The Company also serves a number of state and local governments, foreign governments and U.S. commercial customers. The Company provides services under various contract types, including firm-fixed price (FFP), time-and-materials (T&M), cost-plus-fixed-fee, cost-plus-award-fee and cost-plus-incentive-fee contracts. Our service arrangements typically involve an annual base period of performance followed by renewal periods that are accounted for as separate contracts upon each exercise. The Company recognizes revenue when, or as, we satisfy our performance obligations under a contract. A performance obligation is the unit of account for revenue recognition and refers to a promise in a contract to transfer a distinct service or good to the customer. The majority of the Company’s contracts contain a single performance obligation involving a significant integration of various activities that are performed together to deliver a combined service or solution. Performance obligations may be satisfied over time or at a point in time, but the majority of the Company’s performance obligations are satisfied over time. The Company selects the appropriate measure of progress for revenue recognition based on the nature of the performance obligation, contract type and other pertinent contract terms. Over time performance obligations may involve a series of recurring services, such as network operations and maintenance, operation and program support services, IT outsourcing services, and other IT arrangements where the Company is standing ready to provide support, when-and-if needed. Such performance obligations are satisfied over time because the customer simultaneously receives and consumes the benefits of our performance as services are provided. Alternatively, over time performance obligations may involve the completion of a contract deliverable. Examples include systems integration, network engineering, network design, and engineering and build services. Deliverable-based performance obligations are satisfied over time when the Company’s performance creates or enhances an asset that is controlled by the customer, or when the Company’s performance creates an asset that is customized to the customer’s specifications and the Company has a right to payment, including profit, for work performed to date. For recurring services performance obligations, the Company measures progress using either a cost input measure (cost-to-cost), a time-elapsed output measure, or the as-invoiced practical expedient. A cost input measure typically is applied to the Company’s cost-reimbursable contracts. Revenue is recognized based on the ratio of costs incurred to total estimated costs at completion. Award or incentive fees are allocated to the distinct periods to which they relate. For fixed-price contracts, a time-elapsed output measure is applied to fixed consideration, such that revenue is recognized ratably over the period of performance. Where fixed-price contracts also provide for reimbursement of certain costs, such as travel or other direct costs, consideration may be attributed only to a distinct subset of time within the performance period. The Company’s time-and-material and fixed price-level of effort contracts generally qualify for the as-invoiced practical expedient. Revenue is recognized in the amount to which the Company has a contractual right to invoice. Contract modifications typically create new enforceable rights and obligations, which are accounted for prospectively. Changes to our estimates of the transaction price are recognized as a cumulative adjustment to revenue. For deliverable-based performance obligations satisfied over time, the Company recognizes revenue using a cost input measure of progress (cost-to-cost), regardless of contract type. Revenue is recognized based on the ratio of costs incurred to total estimated costs at completion, except for certain contracts for which the costs associated with significant materials or hardware procurements are excluded from the measure of progress and revenue is recognized on an adjusted cost-to-cost basis. Contract modifications typically change currently enforceable rights and obligations and are accounted for as a cumulative adjustment to revenue. Changes to our estimates of transaction price are recognized as a cumulative adjustment to revenue. For performance obligations in which the Company does not transfer control over time, we recognize revenue at the point-in-time when the customer obtains control of the related asset, usually at the time of shipment or upon delivery. The Company accrues for shipping and handling costs occurring after the point-in-time control transfers to the customer. Recognizing revenue on long-term contracts involves significant estimates and judgments. The transaction price is the estimated amount of consideration we expect to receive for performance under our contracts. Contract terms may include variable consideration, such as reimbursable costs, award and incentive fees, usage-based fees, service-level penalties, performance bonuses, or other provisions that can either increase or decrease the transaction price. Variable amounts generally are determined upon our achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. When making our estimates, the Company considers the customer, contract terms, the complexity of the work and related risks, the extent of customer discretion, historical experience and the potential of a significant reversal of revenue. The Company includes variable consideration in the transaction price only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimating costs at completion is complex due to the nature of the services being performed and the length of certain contracts. Contract costs generally include direct costs, such as labor, subcontract costs and materials, and indirect costs identifiable with or allocable to a specific contract. Management must make assumptions regarding the complexity of the work to be performed, the schedule and associated tasks, labor productivity and availability, increases in wages and prices of materials, execution by our subcontractors, overhead cost rates, and other variables. Contract costs incurred for U.S. government contracts, including indirect costs, are subject to audit and adjustment by the Defense Contract Audit Agency ("DCAA"). Contract fulfillment costs are expensed as incurred except for certain costs incurred for transition, set-up or other fulfillment activities, which are capitalized and amortized on a straight-line basis over the expected period of benefit, which generally includes the base contract period of performance and anticipated renewal periods. The Company provides for anticipated losses on contracts with the U.S. government by recording an expense for the total expected loss during the period in which the losses are first determined. For contracts with multiple performance obligations, the Company allocates transaction price to each performance obligation based on the relative standalone selling price of each distinct performance obligation within the contract. Because the Company typically provides customized services and solutions that are specific to a single customer’s requirements, standalone selling price is most often estimated based on expected costs plus a reasonable profit margin. Changes in Estimates on Contracts Changes in estimates of revenues, cost of revenues or profits related to performance obligations satisfied over time are recognized in operating income in the period in which such changes are made for the inception-to-date effect of the changes. Changes in these estimates can routinely occur over the performance period for a variety of reasons, which include: changes in scope; changes in cost estimates due to unanticipated cost growth or reassessments of risks impacting costs; changes in the estimated transaction price, such as variable amounts for incentive or award fees; and performance being better or worse than previously estimated. In cases when total expected costs exceed total estimated revenues for a performance obligation, the Company recognizes the total estimated loss in the quarter identified. Total estimated losses are inclusive of any unexercised options that are probable of award, only if they increase the amount of the loss. Aggregate changes in these estimates recognized in operating income were: Year Ended January 29, January 31, February 1, (in millions, except per share amounts) Favorable adjustments $ 41 $ 39 $ 30 Unfavorable adjustments (32) (17) (13) Net favorable adjustments 9 22 17 Income tax effect (2) (4) (4) Net favorable adjustments, after tax 7 18 13 Basic EPS impact $ 0.12 $ 0.31 $ 0.29 Diluted EPS impact $ 0.12 $ 0.31 $ 0.29 Revenues were $21 million, $23 million, and $8 million higher for fiscal 2021, 2020, and 2019, respectively, due to net revenue recognized from performance obligations satisfied in prior periods. Disaggregation of Revenues The Company's revenues are generated primarily from long-term contracts with the U.S. government including subcontracts with other contractors engaged in work for the U.S. government. The Company disaggregates revenues by customer, contract-type and prime vs. subcontractor to the federal government. Disaggregated revenues by customer was as follows: Year Ended January 29, 2021 January 31, 2020 February 1, 2019 (in millions) Department of Defense $ 3,292 $ 3,330 $ 2,805 Other federal government agencies 3,611 2,920 1,707 Commercial, state and local 153 129 147 Total $ 7,056 $ 6,379 $ 4,659 Disaggregated revenues by contract-type was as follows: Year Ended January 29, 2021 January 31, 2020 February 1, 2019 (in millions) Cost reimbursement $ 3,773 $ 3,644 $ 2,306 Time and materials (T&M) 1,557 1,280 1,086 Firm-fixed price (FFP) 1,726 1,455 1,267 Total $ 7,056 $ 6,379 $ 4,659 Disaggregated revenues by prime vs. subcontractor was as follows: Year Ended January 29, 2021 January 31, 2020 February 1, 2019 (in millions) Prime contractor to federal government $ 6,337 $ 5,662 $ 4,178 Subcontractor to federal government 566 588 334 Other 153 129 147 Total $ 7,056 $ 6,379 $ 4,659 Contract Balances Timing of revenue recognition may differ from the timing of billing and cash receipts from customers. Amounts are invoiced as work progresses, typically biweekly or monthly in arrears, or upon achievement of contractual milestones. We record a contract asset when revenue is recognized prior to invoicing, or a contract liability when cash is received in advance of recognizing revenue. A contract asset is a right to consideration that is conditional upon factors other than the passage of time. Contract assets include unbillable receivables and contract retentions, but exclude billed and billable receivables. Billed and billable receivables are rights to consideration, which are unconditional other than to the passage of time. Contract liabilities include customer advances, billings in excess of revenues and deferred revenue. Contract assets and liabilities are recorded net on a contract-by-contract basis and are generally classified as current based on our contract operating cycle. Deferred revenue attributable to long-term contract material renewal options may be classified as non-current when the option renewal period will not occur within one year of the balance sheet date. Contract balances for the periods presented were as follows: Balance Sheet line item January 29, January 31, (in millions) Billed and billable receivables, net (1) Receivables, net $ 600 $ 720 Contract assets - unbillable receivables Receivables, net 362 379 Contract assets - contract retentions Other assets 18 17 Contract liabilities - current Other accrued liabilities 82 41 Contract liabilities - non-current Other long-term liabilities $ 17 $ 10 (1) Net of allowance of $3 million and $4 million as of January 29, 2021 and January 31, 2020, respectively. The changes in the Company's contract assets and contract liabilities during the current period primarily results from the acquisition of Unisys Federal in fiscal 2021 and timing differences between the Company's performance, invoicing and customer payments. During the twelve months ended January 29, 2021 and January 31, 2020, the Company recognized revenues of $30 million and $23 million relating to amounts that were included in the opening balance of contract liabilities as of January 31, 2020 and February 1, 2019, respectively. Deferred Costs Certain eligible costs, typically incurred during the initial phases of our service contracts, are capitalized when the costs relate directly to the contract, are expected to be recovered, and generate or enhance resources to be used in satisfying the performance obligation. These costs primarily consist of transition and set-up costs. Capitalized fulfillment costs are amortized on a straight-line basis over the expected period of benefit, which generally includes the contract base period and anticipated renewals. The Company defers fulfillment costs incurred to transfer service to a customer prior to the establishment of a contract provided recovery is probable. These pre-contract costs are typically expensed upon contract award unless they are eligible for capitalization. The Company performs periodic reviews to assess the recoverability of deferred contract transition and setup costs. The carrying amount of the asset is compared to the remaining amount of consideration the Company expects to receive for the services to which the asset relates, less the costs that relate directly to providing those services that have not yet been recognized. If the carrying amount is not recoverable, an impairment loss is recognized. Deferred costs for the periods presented were as follows: Balance Sheet line item January 29, January 31, (in millions) Pre-contract costs Other current assets $ 2 $ 3 Fulfillment costs - non-current Other assets $ 15 $ 12 Pre-contract costs of $8 million and $3 million were expensed during the twelve months ended January 29, 2021 and January 31, 2020, respectively. Fulfillment costs of $4 million and $3 million were amortized during the twelve months ended January 29, 2021 and January 31, 2020, respectively. Remaining Performance Obligations As of January 29, 2021, the Company had $4.9 billion of remaining performance obligations. Remaining performance obligations exclude any variable consideration that is allocated entirely to unsatisfied performance obligations on our supply chain contracts. The Company expects to recognize revenue on approximately 85% of the remaining performance obligations over the next 12 months and approximately 90% over the next 24 months, with the remaining recognized thereafter.

Business Combinations [Abstract]
Acquisitions	Acquisitions: Unisys Federal Acquisition On March 13, 2020, the Company completed the acquisition of Unisys Federal, a former operating unit of Unisys Corporation. Unisys Federal provides infrastructure modernization, cloud migration, managed services, and enterprise IT-as-a-service solutions to U.S. federal civilian agencies and the Department of Defense. This strategic acquisition enhances our capabilities in government priority areas, expands our portfolio of intellectual property and technology-driven offerings, and increases our access to current and new customers. The Company purchased substantially all of the assets and liabilities of Unisys Federal for an aggregate purchase price of $1.2 billion. The Company used the net proceeds from its offering of Senior Notes and borrowings under the Term Loan B2 Facility (as discussed in Note 11), proceeds from the sale of receivables under its MARPA Facility (as discussed in Note 14), and cash on its balance sheet to finance the acquisition and pay related fees and expenses. The purchase price was allocated, on a preliminary basis, among assets acquired and liabilities assumed at fair value on the acquisition date, March 13, 2020, based on the best available information, with the excess purchase price recorded as goodwill. During fiscal 2021, the Company adjusted the preliminary purchase price resulting in a $39 million net increase to goodwill. The measurement period adjustments included: $6 million increase to the purchase price associated with the final net working capital adjustment; $67 million increase to other long-term liabilities associated with off-market customer contracts; $26 million net increase to intangible assets; $6 million increase to deferred tax assets; $1 million increase to prepaid expenses; and $1 million decrease to other accrued liabilities. The Company has completed the purchase accounting valuation for this transaction and recorded final purchase accounting entries as follows: (in millions) Receivables $ 114 Prepaid expenses 15 Goodwill 654 Intangible assets 574 Property, plant, and equipment 4 Operating lease right of use assets 43 Other assets 7 Total assets acquired 1,411 Accounts payable 42 Accrued vacation 7 Other accrued liabilities 62 Operating lease liabilities 30 Other long-term liabilities 68 Total liabilities assumed 209 Net assets acquired $ 1,202 Amount of tax deductible goodwill $ 593 Goodwill resulting from the acquisition of Unisys Federal was primarily associated with intellectual capital, an acquired assembled work force, and future customer relationships. The identifiable intangible assets and a portion of the goodwill acquired by the Company are amortizable for tax purposes. The following table summarizes the fair value of intangible assets and the related weighted-average useful lives as of the acquisition date: Amount Weighted-Average Amortization Period (in millions) (in years) Customer relationships $ 520 13 Backlog 47 1 Developed technology 7 1 Total intangible assets $ 574 12 The backlog intangible asset is comprised solely of funded backlog as of the acquisition date. The customer relationships intangible asset consists of unfunded backlog as of the acquisition date and estimated future renewals and recompetes. The backlog and customer relationships intangible assets were valued using the excess earnings method (income approach) in which the value is derived from an estimation of the after-tax cash flows specifically attributable to the intangible asset being valued. The analysis included assumptions for projections of revenues and expenses, tax rates, contributory asset charges, discount rates, and a tax amortization benefit. The developed technology asset was valued using the relief from royalty method (income approach) in which the value is derived by estimation of the after-tax royalty savings attributable to owning the developed technology asset. Assumptions in this analysis included projections of revenues, royalty rates representing costs avoided due to ownership of the developed technology asset, discount rates, a tax amortization benefit, and future obsolescence of the technology. The Company recorded a $67 million provision for certain off-market customer contracts whose terms are unfavorable compared to the current market terms as of the acquisition date. An income approach was used to estimate fair value, involving estimates for future costs to complete the remaining performance under the contract as well as a market participant profit rate of return. The provision for off-market customer contracts is included in other long-term liabilities and will be amortized over the remaining contractual terms as an increase to revenue. Amortization for the fiscal year ended January 29, 2021, was $15 million. Amortization for the next four years is expected to be as follows: $18 million in 2022, $18 million in 2023, $14 million in 2024, and $2 million in 2025. The Company incurred $49 million in acquisition-related costs associated with the acquisition of Unisys Federal, including $27 million of debt issue costs (as discussed in Note 11). Acquisition-related costs of $2 million were incurred in the fourth quarter of fiscal 2020. The amount of Unisys Federal's revenue included in the consolidated statements of income for the twelve months ended January 29, 2021, was $669 million, and the amount of net income attributable to common stockholders included in the consolidated statements of income for the twelve months ended January 29, 2021, was $62 million. The following unaudited pro forma financial information presents the combined results of operations for Unisys Federal and the Company for the twelve months ended January 29, 2021 and January 31, 2020, respectively: Year Ended January 29, January 31, (in millions) Revenues $ 7,146 $ 7,105 Net income attributable to common stockholders $ 258 $ 193 The unaudited pro forma combined financial information presented above has been prepared from historical financial statements that have been adjusted to give effect to the acquisition of Unisys Federal as though it had occurred on February 2, 2019. They include adjustments for intangible asset amortization; interest expense and debt issuance costs on long-term debt; acquisition and other transaction costs; and certain costs allocated from the former parent. The unaudited pro forma financial information is not intended to reflect the actual results of operations that would have occurred if the acquisition had occurred on February 2, 2019, nor is it indicative of future operating results. Engility Acquisition On January 14, 2019, the Company completed the acquisition of Engility Holdings, Inc., a leading provider of integrated solutions and services supporting U.S. government customers in the defense, federal civilian, and intelligence and space communities. The purchase consideration for the acquisition of Engility was as follows: (in millions) Common stock issued to Engility shareholders (1) $ 1,086 Converted vesting stock awards assumed (2) 22 Cash consideration paid to extinguish Engility outstanding debt 1,052 Purchase price $ 2,160 (1) Represents approximately 16.8 million new shares of SAIC common stock issued to Engility shareholders prior to the market opening on January 14, 2019, using the SAIC share price of $65.03 at the close of business on January 11, 2019. (2) Represents the fair value of the converted vesting stock awards assumed attributable to pre-acquisition service. See Note 8. During fiscal 2019, the Company incurred $63 million in acquisition-related costs associated with the acquisition of Engility, including $31 million of debt issue costs, see Note 11, and $2 million in stock issue costs. The amount of Engility's revenue included in the consolidated statements of income for fiscal 2019 was $98 million and the amount of net loss included in the consolidated statements of income for fiscal 2019 was $19 million, which includes $32 million of integration-related costs. The following unaudited pro forma financial information presents the combined results of operations for Engility and the Company for the year ended February 1, 2019: Year Ended February 1, 2019 (in millions) Revenues $ 6,426 Net income attributable to common stockholders $ 260

The remaining liability associated with the restructuring is $4 million and will be settled by the first quarter of fiscal 2022. In fiscal 2019, the Company initiated restructuring activities (the "2019 Restructuring") to realize cost synergies from the integration of Engility, which includes employee termination costs and other costs associated with the optimization and consolidation of facilities. The Company expects to complete restructuring activities in fiscal 2022, incurring total restructuring costs of approximately $52 million, comprised of $40 million for severance and other employee costs and $12 million of other associated costs, such as contract terminations and costs incurred for facility consolidation. Cash paid for severance and other employee costs was $3 million, $12 million, and $25 million during fiscal 2021, fiscal 2020, and fiscal 2019, respectively. Cash paid for other associated costs was $4 million and $7 million during fiscal 2021 and fiscal 2020, respectively, and the Company expects to incur an additional $1 million in fiscal 2022.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets: Goodwill Goodwill had a carrying value of $2,787 million and $2,139 million as of January 29, 2021 and January 31, 2020, respectively. Goodwill increased by $648 million during the twelve months ended January 29, 2021, due to the acquisition of Unisys Federal ($654 million) as discussed in Note 4, partially offset by goodwill allocated to the divestiture of non-strategic international operations ($6 million) as discussed in Note 1.

Property, Plant, and Equipment	Property, Plant, and Equipment:Property, plant, and equipment are carried at cost net of accumulated depreciation and amortization. Purchases of property, plant, and equipment, as well as costs associated with major renewals and betterments, are capitalized. Maintenance, repairs and minor renewals and betterments are expensed as incurred. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts and any resulting gain or loss is recognized. Depreciation and amortization is recognized using the methods and estimated useful lives as follows: Depreciation or amortization method Estimated useful lives (in years) January 29, January 31, (in millions) Computer equipment Straight-line or 3-10 $ 90 $ 90 Capitalized software and software licenses Straight-line or 3-10 45 68 Leasehold improvements Straight-line Shorter of lease term or 10 92 80 Office furniture and fixtures Straight-line or 3-10 17 19 Buildings and improvements Straight-line 40 7 7 Construction in process 14 7 Land 1 1 Property, plant, and equipment 266 272 Accumulated depreciation and amortization (158) (181) Property, plant, and equipment, net $ 108 $ 91 Depreciation and amortization expense for property, plant, and equipment was $32 million, $36 million and $23 million in fiscal 2021, 2020 and 2019, respectively.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation: Engility Acquisition Assumed Awards Upon the acquisition of Engility, all Engility outstanding and unvested equity awards were converted into SAIC vesting stock awards using the same exchange ratio as Engility’s common shareholders (0.45 SAIC share per Engility share). The Company assumed approximately 642,000 converted vesting stock awards with a fair value of $65.03 per share for a total of $42 million, which was bifurcated between pre- and post-combination periods of service in the amount of $22 million and $20 million, respectively. The amount attributable to the pre-combination service period is included in the purchase consideration of Engility. Of the remaining $20 million attributable to the post-combination service period, the Company expensed $2 million, $3 million, and $14 million in fiscal 2021, fiscal 2020, and fiscal 2019, respectively. Plan Summaries Certain of the Company’s employees participate in the following four stock-based compensation plans: “2013 Equity Incentive Plan” (EIP), “Management Stock Compensation Plan,” “2013 Employee Stock Purchase Plan” (ESPP), and the "2012 Long Term Performance Plan" (LTPP) for Engility assumed awards, which are herein referred to together as the “Plans.” The Company issues new shares on the vesting of stock awards or exercise of stock options under these Plans. The EIP provides the Company’s employees and directors the opportunity to receive various types of stock-based compensation and cash awards. The terms of the stock-based awards granted to employees and directors are the same, except that those for directors cliff vest within one year of the grant date. As of January 29, 2021, the Company has outstanding stock options, vested and vesting stock awards, and performance share awards under this plan. Stock options granted under the EIP generally become exercisable 33%, 33%, and 33% after one, two and three years, respectively, while vesting stock awards granted prior to fiscal 2020 generally vest 25%, 25%, 25% and 25% after one, two, three and four years, respectively. Vesting stock awards granted in fiscal 2020 and thereafter generally vest 33%, 33%, and 33% after one, two and three years, respectively. The maximum contractual term for stock options granted under the EIP is ten years, but historically the Company has granted stock options with a seven-year contractual term. Vesting may be accelerated for employees meeting retirement eligibility conditions. Vesting accelerates for eligible officers upon termination of employment, subject to certain conditions set forth in the Company’s Executive Severance, Change in Control and Retirement Policy effective July 1, 2020. Stock-based awards generally provide for accelerated vesting if there is a change in control (as defined in the EIP). Vesting stock awards and performance share awards have forfeitable rights to dividends. In June 2014, the EIP was amended and restated to increase the total authorized shares of common stock for issuance under the EIP from 5.7 million to 8.5 million. The Company grants performance-based stock awards to certain officers and key employees under the EIP. Performance shares are rights to receive shares of the Company’s stock on the satisfaction of service requirements and performance conditions. These awards cliff vest at the end of the third fiscal year following the grant date, subject to meeting the minimum service requirements and the achievement of certain annual and cumulative financial metrics of the Company’s performance, with the number of shares ultimately issued, if any, ranging up to 200% of the specified target shares. If performance is below the minimum threshold level of performance, no shares will be issued. For all performance share awards granted, the annual financial metrics are based on operating cash flows and the cumulative financial metrics are based on a measure of earnings. The Management Stock Compensation Plan provides for awards in share units to eligible employees. Benefits are payable in shares of the Company’s stock that are held in a trust for the purpose of funding benefit payments to the participants. During fiscal 2017 all remaining outstanding awards in the Management Stock Compensation Plan vested. The Board of Directors may at any time amend or terminate the Management Stock Compensation Plan. In the event of a change in control of the Company (as defined by the Management Stock Compensation Plan), participant accounts will be immediately distributed, otherwise participant accounts will generally be distributed upon retirement, based on the participant’s payout election, or upon termination. The Management Stock Compensation Plan does not provide for a maximum number of shares available for future issuance. The Company’s ESPP allows eligible employees to purchase shares of the Company’s stock at a discount of up to 15% of the fair market value on the date of purchase. During the three years ended January 29, 2021, the discount was 5% of the fair market value on the date of purchase for purchases made under the Company’s ESPP, thereby resulting in the ESPP being non-compensatory. As of January 29, 2021, 3.4 million shares of the Company’s stock are authorized for issuance under the ESPP. The LTPP provides certain employees of the Company the opportunity to receive various types of stock-based compensation awards. As of January 29, 2021, the Company has vesting stock awards assumed from the Engility acquisition under this plan. These remaining outstanding vesting stock awards assumed under the LTPP will continue to vest under their original vesting schedule, when granted by Engility prior to the acquisition, and generally cliff vest at the end of the third fiscal year following the grant date. Vesting may be accelerated for employees meeting retirement eligibility conditions. Vesting stock awards under the LTPP have forfeitable rights to dividends. Expense and Related Tax Benefits Recognized Stock-based compensation expense and related tax benefits recognized under the Plans were: Year Ended January 29, January 31, February 1, (in millions) Stock-based compensation expense: Stock options $ 3 $ 4 $ 3 Vesting stock awards 32 29 37 Performance share awards 7 4 5 Total stock-based compensation expense $ 42 $ 37 $ 45 Tax benefits recognized from stock-based compensation $ 14 $ 13 $ 20 Stock Options Stock options are granted with their exercise price equal to the closing market price of the Company’s stock on the last trading day preceding the grant date. Stock option activity for the year ended January 29, 2021 was: Shares of stocks under stock options Weighted-average exercise price Weighted-average remaining contractual term Aggregate intrinsic value (in millions) (in years) (in millions) Outstanding at January 31, 2020 0.7 $ 60.47 3.5 $ 20 Options granted 0.2 74.57 Options forfeited or expired — — Options exercised (0.2) 40.82 Outstanding at January 29, 2021 0.7 $ 68.57 3.9 $ 20 Options exercisable at January 29, 2021 0.5 $ 64.91 2.8 $ 14 Vested and expected to vest as of January 29, 2021 0.7 $ 68.48 3.8 $ 19 As of January 29, 2021 there was $2 million of unrecognized compensation cost, net of estimated forfeitures, related to stock options, which is expected to be recognized over a weighted-average period of 1.1 years. The following table summarizes activity related to exercises of stock options: Year Ended January 29, January 31, February 1, (in millions) Cash received from exercises of stock options $ — $ — $ — Stock exchanged at fair value upon exercises of stock options $ 1 $ 2 $ 1 Tax benefits from exercises of stock options $ 2 $ 3 $ 7 Total intrinsic value of options exercised $ 8 $ 16 $ 24 The fair value of stock option awards granted under the Company’s plan were valued using the Black-Scholes option-pricing model based on the following assumptions: Expected Term --The expected term was calculated from the Company's historical settlement data. Expected Volatility --The expected volatility is based on the historical volatility of the Company over a period commensurate with the expected term of the stock option as of the date of grant. Risk-Free Interest Rate --The risk-free interest rate is based on the yield curve of a zero-coupon U.S. Treasury bond with a maturity equal to the expected term of the stock option on the date of grant. Dividend Yield --The dividend yield assumed over the expected term of the option is calculated based on the most recently announced dividend as of the grant date. The weighted-average grant date fair value and assumptions used to determine the fair value of stock options granted for the periods presented were: Year Ended January 29, January 31, February 1, Weighted-average grant-date fair value $ 17.54 $ 16.88 $ 19.48 Expected term (in years) 3.8 4.2 4.0 Expected volatility 35.5 % 30.0 % 29.0 % Risk-free interest rate 0.3 % 2.2 % 2.5 % Dividend yield 1.8 % 2.0 % 1.6 % Vesting Stock Awards Vesting stock award activity for the year ended January 29, 2021 was: Shares of stock under stock awards Weighted-average grant date fair value (in millions) Unvested January 31, 2020 0.9 $ 74.94 Awards granted 0.6 76.41 Awards forfeited (0.1) 75.34 Awards vested (0.4) 72.64 Unvested January 29, 2021 1.0 $ 76.73 The grant date fair value of vesting stock awards is based on the closing market price of the Company’s stock on the last trading day preceding the grant date. The weighted-average grant date fair value of the vesting stock awards granted for fiscal 2021, fiscal 2020 and fiscal 2019 was $76.41, $76.01 and $84.28, respectively. As of January 29, 2021 there was $39 million of unrecognized compensation cost, net of estimated forfeitures, related to vesting stock awards, which is expected to be recognized over a weighted-average period of 1.3 years. The fair value of vesting stock awards that vested in fiscal 2021, fiscal 2020 and fiscal 2019 was $32 million, $35 million and $60 million, respectively. Performance Share Awards Performance share award activity for the year ended January 29, 2021 was: Shares of stock under performance shares Weighted-average grant date fair value (in millions) Unvested performance shares at January 31, 2020 0.1 $ 81.60 Performance shares granted 0.1 74.40 Performance shares forfeited — — Performance shares vested — — Performance shares adjustment — — Unvested performance shares at January 29, 2021 0.2 $ 76.54 For performance share awards granted in fiscal 2021, the actual number of shares to be issued upon vesting range between 0-200% of the specified target shares. For performance share awards granted prior to fiscal 2021, the actual number of shares to be issued upon vesting range between 0-150% of the specified target shares. The number of performance shares are presented at 100% of the specified target shares in the table above, except for performance shares that vested and performance shares adjustment. Performance shares vested reflects the number of shares to be issued based on the actual achievement of the performance goals for shares that vested during the period. Performance shares adjustment reflects the increase or decrease in the number of performance shares vested compared to the number of performance shares that would have vested at target. The fair value of performance share awards that vested in fiscal 2021 was $5 million. For unvested performance shares as of January 29, 2021 the Company expects to issue 0.2 million shares of stock in the future based on estimated future achievement of the performance goals. The weighted-average grant date fair value of the performance share awards granted for fiscal 2021, fiscal 2020, and fiscal 2019 was $74.40, $79.04 and $85.31, respectively. The grant date fair value of performance share awards is based on the closing market price of the Company’s common stock on the last trading day preceding the grant date. As of January 29, 2021 there was $5.6 million of unrecognized compensation cost, net of estimated forfeitures, related to performance share awards, which is expected to be recognized over a weighted-average period of 1.7 years.

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans: Defined Contribution Plans The Company sponsors the Science Applications International Corporation Retirement Plan (a qualified defined contribution 401(k) plan) and an employee stock ownership plan, in which most employees are eligible to participate. There are a variety of investment options available, including the Company's stock. Engility sponsored the Engility Master Savings Plan, which was a 401(k) plan in which most employees of Engility were eligible to participate. The Engility Master Savings Plan merged into the Science Applications International Corporation Retirement Plan on January 2, 2020. The Science Applications International Corporation Retirement Plan allows eligible participants to contribute a portion of their income through payroll deductions and the Company makes matching company contributions and may also make discretionary contributions. The Company contributions expensed for defined contribution plans were $73 million, $65 million and $46 million in fiscal 2021, 2020 and 2019, respectively. Deferred Compensation Plans The Company has established the Science Applications International Corporation Deferred Compensation Plan (DCP), effective January 1, 2015, providing certain eligible employees and directors an opportunity to defer some or all of their compensation on an unfunded, nonqualified basis. Participant deferrals are fully vested and diversified at the participant’s direction among the investment options offered under the DCP. Participant accounts will be credited with a rate of return based on the performance of the investment options selected. Distributions are made in cash. Deferred balances will be paid on retirement, based on the participant’s payout election, or upon termination. The Company may provide discretionary contributions to participants, but no Company contributions have been made. The Science Applications International Corporation Key Executive Stock Deferral Plan (KESDP) was closed on December 31, 2014, and no further deferrals are allowed. Benefits from the KESDP are payable in shares of the Company’s stock that may be held in trust for the purpose of funding benefit payments to KESDP participants. Vested deferred balances will generally be paid on retirement, based on the participant’s payout election, or upon termination. The Science Applications International Corporation 401(k) Excess Deferral Plan (Excess Plan) was also closed on December 31, 2014, and no further deferrals are allowed. Participant deferrals are fully vested and diversified at the participant’s direction among the investment options offered under the Excess Plan. Deferred balances will generally be paid following retirement or termination. Defined Benefit Plans In connection with the acquisition of Engility on January 14, 2019, SAIC assumed two defined benefit plans sponsored by Engility for certain current and former employees: a Defined Benefit Pension Plan (Pension Plan) and a Retiree Health Reimbursement Account Plan (RHRA Benefit Plan). Membership and participants' calculated pension benefit are frozen in the Pension Plan and membership in the RHRA Benefit Plan is frozen. Our funding policy is to contribute at least the minimum amount required by the Employee Retirement income Security Act of 1974. Additional amounts are contributed to assure that plan assets will be adequate to provide retirement benefits. During fiscal 2022, the Company expects to contribute $1 million to fund the RHRA Benefit Plan. During fiscal 2021, the Company recognized a net gain of $2 million on our retirement plans within other comprehensive loss. The gain was primarily comprised of a $3 million gain due to assumption changes other than discount rates, $2 million gain from the excess in actual investment return over the expected return, and $1 million of settlement charges. During the fourth quarter of fiscal 2021, the Company transferred out $6 million of assets to settle the obligations of certain retirees within the Pension Plan, which resulted in the $1 million of settlement charges. These gains were partially offset by a $4 million increase in liability caused by a decrease in the discount rates. During fiscal 2020, the Company recognized net losses of $5 million and $1 million within other comprehensive (income) loss related to changes in the net benefit obligations for the Pension Plan and RHRA Benefit Plan, respectively. During fiscal 2020, the net loss of $6 million was attributable to a $9 million increase in the projected benefit obligation caused by a decrease in the discount rate, partially offset by an actual investment return in excess of the expected return by $3 million. Net Periodic Benefit Costs The net periodic benefit cost was as follows: Pension Plan RHRA Benefit Plan Year Ended January 29, 2021 January 31, 2020 January 29, 2021 January 31, 2020 (in millions) Interest cost on projected benefit obligation $ 2 $ 3 $ — $ 1 Expected return on plan assets (3) (3) — — Settlement cost 1 — — — Net periodic benefit cost $ — $ — $ — $ 1 Obligations and Funded Status The projected benefit obligation, fair value of plan assets, and funded status for each plan are as follows: Pension Plan RHRA Benefit Plan January 29, 2021 January 31, 2020 January 29, 2021 January 31, 2020 (in millions) Change in benefit obligation: Benefit obligation at beginning of year $ 76 $ 71 $ 17 $ 15 Interest cost 2 3 — 1 Benefits paid (5) (5) (1) (1) Actuarial loss (gain) 3 7 (2) 2 Settlements (6) — — — Benefit obligation at end of year $ 70 $ 76 $ 14 $ 17 Change in plan assets: Fair value of plan assets at beginning of year 53 52 — — Actual return on plan assets 5 6 — — Employer contributions 8 — 1 1 Benefits paid (5) (5) (1) (1) Settlements (6) — — — Fair value of plan assets at end of year $ 55 $ 53 $ — $ — Unfunded status $ 15 $ 23 $ 14 $ 17 Amounts recognized in the consolidated balance sheets consist of: Pension Plan RHRA Benefit Plan January 29, 2021 January 31, 2020 January 29, 2021 January 31, 2020 (in millions) Other accrued liabilities $ — $ — $ 1 $ 1 Other long-term liabilities 15 23 13 16 Net amount recognized $ 15 $ 23 $ 14 $ 17 Assumptions The Company uses the spot rate approach to measure liabilities and interest costs for defined benefit obligations. Under the spot rate approach, the Company uses individual spot rates along the yield curve that correspond with the timing of each benefit payment. The discount rates represent the estimated rate at which we could effectively settle our defined benefit obligations using a high quality bond yield curve. The assumed long-term rate of return on plan assets, which is the average return expected on the funds invested or to be invested to provide future benefits to pension plan participants, is determined by an annual review of historical returns on plan assets. In selecting the expected long-term rate of return on assets used for the Pension Plan, the Company considered its investment return goals stated in the Pension Plan's investment policy. This process included determining expected returns for the various asset classes that comprise the Pension Plan's target asset allocation. The following assumptions were used to determine the benefit obligations and net periodic benefit costs: Pension Plan RHRA Benefit Plan January 29, 2021 January 31, 2020 February 1, 2019 January 29, 2021 January 31, 2020 February 1, 2019 Discount rate 2.47 % 2.87 % 4.06 % 1.86 % 2.56 % 3.82 % Interest cost effective rate 2.47 % 3.70 % N/A 2.27 % 3.58 % N/A Expected rate of return on assets 5.50 % 5.50 % N/A N/A N/A N/A Pension Plan Assets The Company's investment policy includes a periodic review of the Pension Plan's investment in the various asset classes. During 2021, the Company's overall investment strategy is for plan assets to achieve a long-term rate of return of 5.50%, with a wide diversification of asset types, fund strategies and fund managers. The target allocation for the plan assets is 44% in domestic equity securities, 20% international equity, 31% in fixed income securities, and 5% in cash and cash equivalents. The risk management practices include regular evaluations of fund managers to ensure the risk assumed is commensurate with the given investment style and objectives. According to the plan's investment policy, performance will be evaluated across all time periods, with a particular emphasis on longer-term returns relative to associated peers and benchmarks. The fair value measurement of plan assets by category is as follows: January 29, 2021 January 31, 2020 Asset Category Fair Value Hierarchy (in millions) Mutual funds Equity Level 1 $ 37 $ 34 Fixed income Level 1 8 9 Guaranteed deposit account Level 3 3 2 Subtotal 48 45 Collective trust - fixed income (1) Measured at NAV 7 8 Total $ 55 $ 53 (1) Collective trusts are measured at fair value using net asset value (NAV) as a practical expedient and have not been categorized in the fair value hierarchy. Fair Value Measurement Using Significant Unobservable Inputs (Level 3) A reconciliation of the beginning and ending balances of the Guaranteed Deposit Account (GDA) is as follows: Guaranteed Deposit Account (in millions) Balance at February 1, 2019 $ 3 Purchases 13 Sales (14) Balance at January 31, 2020 2 Purchases 12 Sales (11) Balance at January 29, 2021 $ 3 The GDA is designed to provide liquidity and safety of principal with a competitive guaranteed rate of return. The fair value of the GDA approximates the market value of underlying investments by discounting expected future investment cash flow from both investment income and repayment of principal for each investment purchased directly for the defined benefit segment of the General Account. Principal and accumulated interest are fully guaranteed by Prudential Retirement Insurance and Annuity Company (PRIAC). The declared interest rate is announced each year in advance and is determined by PRIAC. The GDA invests in a broadly diversified, fixed-income portfolio within PRIAC's general account. The portfolio is invested in public bonds, commercial mortgages and private placement bonds. Estimated Future Benefit Payments The following table sets forth the expected timing of benefit payments by fiscal year: Fiscal Year Pension Plan RHRA Benefit Plan Total (in millions) 2022 $ 5 $ 1 $ 6 2023 5 1 6 2024 5 1 6 2025 5 1 6 2026 5 1 6 Five subsequent fiscal years $ 22 $ 6 $ 28

Income Taxes	Income Taxes: Substantially all of the Company’s income before income taxes for the three years ended January 29, 2021 is subject to taxation in the United States. The provision for income taxes for each of the periods presented include the following: Year Ended January 29, January 31, February 1, (in millions) Current: Federal $ 34 $ 10 $ 4 State 14 3 10 Deferred: Federal 10 32 17 State 2 12 2 Total $ 60 $ 57 $ 33 A reconciliation of the provision for income taxes to the amount computed by applying the statutory federal income tax rate to income before income taxes for each of the periods presented follows: Year Ended January 29, January 31, February 1, (in millions) Amount computed at the statutory federal income tax rate $ 57 $ 60 $ 36 State income taxes, net of federal tax benefit 13 14 9 Research and development and other federal credits (8) (11) (8) Non-deductible compensation 3 2 3 Non-deductible acquisition costs — — 3 Excess tax benefits for stock-based compensation (3) (4) (9) Other (2) (4) (1) Total $ 60 $ 57 $ 33 Effective income tax rate 22.1 % 20.0 % 19.4 % The effective income tax rate for fiscal 2021 is higher than fiscal 2020 primarily due to less research and development credits in fiscal 2021 because fiscal year 2020 included the benefit from multiple years and smaller excess tax benefits from stock-based compensation in fiscal 2021. In fiscal 2020, we recognized $6 million of tax benefits related to research and development credits for fiscal years 2016 - 2019 and $5 million related to the 2020 tax year. The effective income tax rate for fiscal 2020 is consistent with the rate in fiscal 2019 due to smaller excess tax benefits from stock-based compensation were partially offset by increased research and development credits in fiscal 2020. Deferred income taxes are recorded for differences in the basis of assets and liabilities for financial reporting purposes and tax reporting purposes. Deferred tax assets (liabilities) were comprised of: January 29, January 31, (in millions) Accrued vacation and bonuses $ 33 $ 21 Accrued liabilities 16 20 Deferred compensation 20 23 Stock awards 11 11 Net operating loss and other carryforwards 105 117 Fixed asset basis differences — 2 Deferred revenue 14 — Lease liability 65 54 Payroll tax deferral 11 — Accumulated other comprehensive loss 30 23 Valuation allowance (7) (5) Total deferred tax assets 298 266 Deferred revenue — (1) Purchased intangible assets (198) (177) Fixed asset basis difference (4) — Right of use assets (61) (48) Total deferred tax liabilities (263) (226) Net deferred tax assets $ 35 $ 40 Net deferred tax assets are presented in other assets on the consolidated balance sheets. Deferred tax assets for both periods presented include state tax credit carryforwards for which the Company has set up a valuation allowance. The changes in the unrecognized tax benefits, excluding accrued interest and penalties, were: Year Ended January 29, January 31, February 1, (in millions) Unrecognized tax benefits at beginning of the year $ 51 $ 13 $ 7 Additions for acquired unrecognized tax benefits — — 3 Additions for tax positions related to prior years 8 32 1 Additions for tax positions related to the current year 9 8 2 Reductions for prior year tax positions related to statute expiration (2) (2) — Unrecognized tax benefits at end of the year $ 66 $ 51 $ 13 Unrecognized tax benefits that, if recognized, would affect the effective income tax rate $ 66 $ 48 $ 9 Over the next 12 months, the Company does not expect a significant increase or decrease in the unrecognized tax benefits recorded at January 29, 2021. During the year ended January 29, 2021, we recognized an increase in unrecognized tax benefits of approximately $17 million related to an increase in available tax credits in fiscal year 2021. The Company recognizes net interest and penalties as a component of income tax expense and for the periods presented, there was not a material amount of current interest and penalties recognized. The Company has filed income tax returns in the U.S. and various state jurisdictions, which may be subject to routine compliance reviews by the Internal Revenue Service ("IRS") and other taxing authorities. While the Company believes it has adequate accruals for uncertain tax positions, the tax authorities may determine that the Company owes taxes in excess of recorded accruals or the recorded accruals may be in excess of the final settlement amounts agreed to by tax authorities. The Company’s tax returns for fiscal years 2016 through 2020 remain subject to examination by the IRS and various other tax jurisdictions. The Company is currently under examination by the IRS for fiscal years 2016 and 2017. The Company is also subject to examination for the returns of Engility from calendar year 2016 through the short pre-acquisition period ended January 13, 2019, although net operating losses from all years are subject to examinations and adjustments for at least three years following the year in which the attribute is used. The Company is responsible for Engility's tax liabilities relating to all open pre and post acquisition years.

The Revolving Credit Facility is available to the Company through October 2023 and there is no balance outstanding as of January 29, 2021. Any obligations under the Credit Facility are secured by liens on substantially all of the assets of the Company and its subsidiaries. As of January 29, 2021, the Company was in compliance with the covenants under its Credit Facility. During fiscal 2019, the Company entered into the Third Amended and Restated Credit Agreement (Third Amended Credit Agreement) in anticipation of the acquisition of Engility. In connection with the Third Amended Credit Agreement, the Company increased the capacity of its existing Revolving Credit Facility to $400 million, funded a senior secured Term Loan B Facility due October 2025 in the amount of $1.1 billion, and funded the Term Loan A Facility due October 2023 in the amount of $1.1 billion. The proceeds were used to repay all indebtedness outstanding under the previous credit facility, to partially finance the acquisition of Engility, and for general corporate purposes. The Company incurred $31 million of debt issue costs associated with the Third Amended Credit Agreement. The Company recognized $5 million in expenses associated with the Third Amended Credit Agreement, which is included in interest expense and includes a $4 million loss on extinguishment of debt. The Company deferred $26 million in financing fees that are amortized to interest expense utilizing the effective interest method. Borrowings under the Term Loan A Facility due October 2023 amortize quarterly beginning on January 31, 2020 at 1.25% of the original borrowed amount thereunder, with such quarterly amortization payments increasing to 1.875% on January 31, 2021 and then to 2.50% on January 31, 2022. Beginning January 31, 2019, the Term Loan B Facility due October 2025 amortizes quarterly at 0.25% of the original borrowed amount. Beginning in fiscal year 2020, the scheduled principal repayments for the Term Loan A and Term Loan B facilities may be further reduced or eliminated by annual mandatory prepayments of a portion of SAIC’s Excess Cash Flow (as defined in the Third Amended Credit Agreement). Mandatory principal prepayments are allocated to Term Loan A and Term Loan B facilities on a pro rata basis and reduce the remaining scheduled principal installments for each facility. Voluntary principal prepayments may be applied to either or both loans at the Company’s direction. During fiscal year 2020, the Company made $150 million of voluntary principal prepayments on the Term Loan A Facility due October 2023. During fiscal 2020, the Company borrowed and repaid $100 million under the Revolving Credit Facility. Borrowings under the Third Amended Credit Agreement bear interest at a variable rate of interest based on LIBOR or a base rate, plus in each case an applicable margin. Applicable margins with respect to borrowings under the Term Loan B Facility due October 2025 are 1.75% for LIBOR loans and 0.75% for base rate loans. Applicable margins with respect to borrowings under the Term Loan A Facility due October 2023 and the Revolving Credit Facility due October 2023 range from 1.25% to 2.00% for LIBOR loans and 0.25% to 1.00% for base rate loans, in each case based on the then applicable Leverage Ratio (as defined in the Third Amended Credit Agreement). The Company also pays a commitment fee with respect to undrawn amounts under the Revolving Credit Facility due October 2023 ranging from 0.20% to 0.35%. The Third Amended Credit Agreement contains certain restrictive covenants applicable to the Company and its subsidiaries including a requirement to maintain a Senior Secured Leverage Ratio (as defined in the Third Amended Credit Agreement) of not greater than 3.75 to 1.00 until the effectiveness of the acquisition of Engility, not greater than 4.50 to 1.00 upon the effectiveness of the acquisition and for the succeeding six fiscal quarters, and not greater than 4.00 to 1.00 thereafter, unless a Permitted Acquisition (as defined in the Third Amended Credit Agreement) occurs in which case not greater than 4.25 to 1.00 for three consecutive quarters following such a transaction. On March 13, 2020, the Company entered into the Second Amendment to the Third Amended and Restated Credit Agreement (Second Amendment), which established, among other things, a new $600 million senior secured term loan "B" credit facility commitment (the Term Loan B2 Facility due March 2027) that was funded in full contemporaneously with the closing of the acquisition of Unisys Federal (see Note 4). The Term Loan B2 Facility due March 2027 bears interest at a variable rate of interest based on LIBOR or a base rate, plus, an applicable margin of 2.25% for LIBOR loans and 1.25% for base rate loans. Effective upon funding the Term Loan B2 Facility due March 2027, the applicable margin for the Term Loan B Facility due October 2025 was increased from 1.75% to 1.875% for LIBOR loans and from 0.75% to 0.875% for base rate loans. Borrowings under the Term Loan B2 Facility due March 2027 amortize quarterly beginning on July 31, 2020 at 0.25% of the original borrowed amount with the remaining unamortized balance due in full upon its maturity, March 13, 2027. The Term Loan B2 Facility due March 2027 is subject to the same mandatory prepayments as the Company’s existing term loans under the Credit Facility and is subject to the same covenants and events of default as the Company's Term Loan B Facility due October 2025. During the twelve months ended January 29, 2021, the Company made voluntary principal prepayments on the Term Loan B2 Facility due March 2027 of $325 million. The Company wrote off debt issuance costs associated with the voluntary principal prepayments of $8 million. On March 13, 2020, to partially finance the acquisition of Unisys Federal, the Company issued $400 million of unsecured 4.875% Senior Notes due 2028 (the Senior Notes) through a private offering. Interest is payable semi-annually on April 1 and October 1 of each year, commencing on October 1, 2020, and the principal is due on April 1, 2028. The Company incurred $27 million of debt issue costs associated with the Second Amendment, the issuance of the Senior Notes, and an undrawn bridge facility that terminated upon the consummation of the acquisition of Unisys Federal. The Company deferred $22 million of financing fees and recognized $5 million of expenses associated with the undrawn bridge facility, which is included in interest expense. Deferred financing fees are amortized to interest expense utilizing the effective interest method. Maturities of long-term debt as of January 29, 2021 are: Fiscal Year Ending Total (in millions) 2022 $ 68 2023 147 2024 661 2025 10 2026 984 Thereafter 672 Total principal payments $ 2,542

Receivables [Abstract]
Sales of Receivables	Sale of Receivables: On January 21, 2020 the Company entered into a Master Accounts Receivable Purchase Agreement (MARPA Facility) with MUFG Bank, Ltd. (the Purchaser) for the sale of up to a maximum amount of $200 million of certain designated eligible receivables with the U.S. government. On March 17, 2020, the Company amended the MARPA Facility to increase the aggregate facility limit from $200 million to $300 million. The receivables sold under the MARPA Facility are without recourse for any U.S. government credit risk. The MARPA Facility had an initial term of one year, but effective with the renewal on January 21, 2021 will automatically renew each year unless one of the parties gives prior notice to terminate. The Company accounts for these receivable transfers under the MARPA Facility as sales under ASC 860, Transfers and Servicing, and removes the sold receivables from its balance sheet. The fair value of the sold receivables approximated their book value due to their short-term nature. The Company does not retain an ongoing financial interest in the transferred receivables other than cash collection and administrative services. The Company estimated that its servicing fee was at fair value and therefore has not recognized a servicing asset or liability as of January 29, 2021. Proceeds from the sale of receivables are reflected as cash flows from operating activities on the consolidated statements of cash flows. During the twelve months ended January 29, 2021, the Company incurred purchase discount fees of $2 million, which are presented in other (income) expense, net on the consolidated statements of income. MARPA Facility activity consisted of the following: Year Ended January 29, 2021 (in millions) Beginning balance $ — Sale of receivables 3,226 Cash collections (3,041) Increase to cash flows from operating activities 185 Cash collected, not remitted to Purchaser (1) (25) Remaining sold receivables $ 160

Leases [Abstract]
Operating Leases	Leases: The Company occupies most of its facilities under operating leases. Certain equipment also is leased under short-term or cancelable operating leases. Effective upon the adoption of ASU 2016-02, the Company recognizes a right of use (ROU) asset and a lease liability upon the commencement of its operating leases. The initial lease liability is equal to the future fixed minimum lease payments discounted using the Company’s incremental borrowing rate, on a secured basis. The lease term includes option renewal periods and early termination payments when it is reasonably certain that the Company will exercise those rights. The initial measurement of the ROU asset is equal to the initial lease liability plus any initial direct costs and prepayments, less any lease incentives. The Company recognizes lease costs on a straight-line basis over the remaining lease term, except for variable lease payments that are expensed in the period in which the obligation for those payments is incurred. For its facility leases, the Company combines and accounts for lease and non-lease components together as a single component. The Company does not recognize lease liabilities and ROU assets for facility leases with original terms of 12 months or less. ROU assets are evaluated for impairment as a long-lived asset. Total operating lease cost is comprised of the following: Year Ended January 29, 2021 January 31, 2020 (in millions) Operating lease cost $ 74 $ 64 Variable lease cost 21 15 Short-term lease cost 35 4 Sublease income (2) (3) Total lease cost $ 128 $ 80 Lease cost and sublease income are included primarily in cost of revenues and SG&A, except for $1 million and $5 million of impairment of right of use assets for fiscal 2021 and fiscal 2020, respectively, that are included in acquisition and integration costs. Rental expense for facilities and equipment under ASC 840 was $46 million in fiscal 2019. The Company's ROU assets and lease liabilities consisted of the following: Balance Sheet line item January 29, 2021 January 31, 2020 (in millions) Operating lease ROU asset Operating lease right of use assets $ 236 $ 190 Operating lease current liability Other accrued liabilities 49 34 Operating lease non-current liability Operating lease liabilities 205 172 Total operating lease liabilities $ 254 $ 206 Other supplemental operating lease information consists of the following: Year Ended January 29, 2021 January 31, 2020 (in millions) Cash paid for amounts included in the measurement of operating lease liabilities $ 77 $ 64 ROU assets obtained in exchange for new operating lease obligations $ 110 $ 79 Maturities of operating lease liabilities as of January 29, 2021 were as follows: Fiscal Year Ending Total (in millions) 2022 $ 57 2023 58 2024 47 2025 37 2026 29 Thereafter 54 Total minimum lease payments 282 Less: imputed interest (28) Present value of operating lease liabilities $ 254 The weighted-average remaining lease term and the weighted-average discount rate was 5 years and 3.5% as of January 29, 2021, respectively, and 6 years and 4.5% as of January 31, 2020, respectively. The Company leases IT equipment and hardware to its customers. All of the Company’s lessor arrangements are operating leases. Operating lease revenue is recognized on a straight-line basis over the term of the lease. During the twelve months ended January 29, 2021, operating lease income was $40 million. Operating lease income is reported as revenue on the consolidated statements of income. As of January 29, 2021, the undiscounted future payments from our sublease arrangements is $12 million, which are expected to be received during fiscal 2022.

Segment Reporting [Abstract]
Business Segment Information	Business Segment Information: The Company is organized as a matrix comprised of three customer facing operating segments supported by a strategy, growth and innovation organization. The three operating segments are responsible for customer relationships, business development and program management, and delivery and execution, while the strategy, growth, and innovation organization manages the development of our offerings, solutions and capabilities. Each of the Company’s three operating segments is focused on providing the Company’s comprehensive technical, engineering and enterprise IT service offerings to one or more agencies of the U.S federal government. The Company's operating segments are aggregated into one reportable segment because they have similar economic characteristics and meet the other aggregation criteria within the accounting standard on segment reporting, including similarities in the nature of the services provided, methods of service delivery, customers served and the regulatory environment in which they operate. Substantially all of the Company’s revenues were generated by, and tangible long-lived assets owned by, entities located in the United States. As such, financial information by geographic location is not presented. In each of fiscal 2021, 2020, and 2019 over 95% of our total revenues were attributable to prime contracts with the U.S. government or to subcontracts with other contractors engaged in work for the U.S. government.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Commitments and Contingencies	Legal Proceedings and Commitments and Contingencies: Legal Proceedings The Company is involved in various claims and lawsuits arising in the normal conduct of its business, none of which the Company’s management believes, based on current information, is expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. AAV Termination for Convenience On August 27, 2018, the Company received a stop-work order from the United States Marine Corps on the Assault Amphibious Vehicle (AAV) contract and on October 3, 2018 the program was terminated for convenience by the customer. The Company is continuing to negotiate with the Marine Corps to recover costs associated with the termination. Beginning in fiscal 2018, the Company entered into contracts with various vendors for long-lead time materials that would be necessary to complete the low-rate initial production (LRIP) phase of the program, including portions of the LRIP phase that had not yet been awarded. As a result of the program termination, the Company recognized an inventory provision for long-lead items during fiscal 2019, see Note 1. Scitor Acquisition On May 4, 2015, the Company completed the acquisition of Scitor Holdings, Inc. ("Scitor"), a leading global provider of technical services to the U.S. intelligence community and other U.S. government customers. Purchase consideration paid to acquire Scitor was $764 million (net of cash acquired), including $43 million that was deposited to escrow accounts. In August 2015, $3 million was released from escrow to the sellers after finalizing the working capital adjustment and another $13 million was released in September 2016 that was held to secure a portion of the sellers’ indemnification obligations. During the first quarter of fiscal 2019, the Company received a $6 million distribution from escrow to settle a claim, which was recognized as a reduction to selling, general and administrative costs. There is no remaining amount in escrow. Government Investigations, Audits and Reviews The Company is routinely subject to investigations and reviews relating to compliance with various laws and regulations with respect, in particular, to its role as a contractor to federal, state and local government customers and in connection with performing services in countries outside of the United States. U.S. government agencies, including the DCAA, the Defense Contract Management Agency and others, routinely audit and review a contractor’s performance on government contracts, indirect rates and pricing practices, and compliance with applicable contracting and procurement laws, regulations and standards. They also review the adequacy of the contractor’s compliance with government standards for its business systems. Adverse findings in these investigations, audits, or reviews can lead to criminal, civil or administrative proceedings, and the Company could face disallowance of previously billed costs, penalties, fines, compensatory damages, and suspension or debarment from doing business with governmental agencies. Due to the Company’s reliance on government contracts, adverse findings could also have a material impact on the Company’s business, including its financial position, results of operations and cash flows. The indirect cost audits by the DCAA of the Company’s business remain open for certain prior years and the current year. Although the Company has recorded contract revenues based on an estimate of costs that the Company believes will be approved on final audit, the Company does not know the outcome of any ongoing or future audits. If future completed audit adjustments exceed the Company’s reserves for potential adjustments, the Company’s profitability could be materially adversely affected. The Company has recorded reserves for estimated net amounts to be refunded to customers for potential adjustments for indirect cost audits and compliance with CAS. As of January 29, 2021, the Company has recorded a total liability of $46 million, which is presented in other accrued liabilities on the consolidated balance sheets.

Business Overview and Summary_2

Business Overview and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 29, 2021
Accounting Policies [Abstract]
Segment Reporting	The Company is organized as a matrix comprised of three customer facing operating segments supported by a strategy, growth and innovation organization. Each of the Company’s three customer facing operating segments is focused on providing the Company’s comprehensive technical, engineering and enterprise IT service offerings to one or more agencies of the U.S federal government. The Company's operating segments are aggregated into one reportable segment for financial reporting purposes, see Note 16.
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation References to “financial statements” refer to the consolidated financial statements of the Company, which include the statements of income and comprehensive income, balance sheets, statements of equity and statements of cash flows. These financial statements were prepared in accordance with U.S. generally accepted accounting principles (GAAP). All intercompany transactions and account balances within the Company have been eliminated. Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Significant estimates inherent in the preparation of the financial statements may include, but are not limited to estimated profitability of long-term contracts, income taxes, fair value measurements, fair value of goodwill and other intangible assets, pension and defined benefit plan obligations, and contingencies. Estimates have been prepared by management on the basis of the most current and best available information at the time of estimation and actual results could differ from those estimates.
Reporting Periods	Reporting Periods The Company utilizes a 52/53 week fiscal year ending on the Friday closest to January 31, with fiscal quarters typically consisting of 13 weeks. Fiscal 2019 began on February 3, 2018 and ended on February 1, 2019, fiscal 2020 began on February 2, 2019 and ended on January 31, 2020, and fiscal 2021 began on February 1, 2020 and ended on January 29, 2021.
Stock-based Compensation	Stock-based CompensationThe Company issues stock-based awards as compensation to employees and directors. Stock-based awards include stock options, vesting stock awards and performance share awards. These awards are accounted for as equity awards. The Company recognizes stock-based compensation expense net of estimated forfeitures on a straight-line basis over the underlying award’s requisite service period, as measured using the award’s grant date fair value. For performance share awards, the Company reassesses the probability of achieving the performance conditions at each reporting period end and adjusts compensation expense based on the number of shares the Company expects to ultimately issue.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method of accounting, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Under this method, changes in tax rates and laws are recognized in income in the period such changes are enacted. The provision for federal, state, local and foreign income taxes is calculated on income before income taxes based on current tax law and includes the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Such provision differs from the amounts currently payable because certain items of income and expense are recognized in different reporting periods for financial reporting purposes than for income tax purposes. Recording the provision for income taxes requires management to make significant judgments and estimates for matters for which the ultimate resolution may not become known until the final resolution of an examination by taxing authorities or the statute of limitations lapses. Additionally, recording liabilities for uncertainty in income taxes involves significant judgment in evaluating the Company’s tax positions and developing the best estimate of the taxes ultimately expected to be paid. Tax penalties and interest are included in income tax expense. The Company records net deferred tax assets to the extent these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent results of operations. If it is determined that the Company would be able to realize the deferred income tax assets in the future in excess of their net recorded amount or would no longer be able to realize the deferred income tax assets in the future as currently recorded, an adjustment would be made to the valuation allowance, which would decrease or increase the provision for income taxes. The Company has also recognized liabilities for uncertainty in income taxes when it is more likely than not that a tax position will not be sustained on examination and settlement with various taxing authorities. Liabilities for uncertainty in income taxes are measured based on the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Deferred tax assets and liabilities are netted by taxable jurisdiction and classified as noncurrent on the consolidated balance sheets.
Costs Allocated to Contracts	Costs Allocated to Contracts The Company classifies indirect costs as overhead (included in cost of revenues) or general and administrative expenses in the same manner as such costs are defined in the Company’s Disclosure Statements under U.S. government Cost Accounting Standards (CAS).
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents are comprised of cash in banks and highly liquid instruments, which primarily consist of bank deposits and investments in institutional money market funds. The Company includes outstanding payments within cash and cash equivalents and accounts payable on the consolidated balance sheets and as of January 29, 2021 and January 31, 2020 these amounts were $25 million and $54 million, respectively. The Company does not invest in high yield or high risk securities. The cash in bank accounts at times may exceed federally insured limits.
Receivables	Receivables Receivables include billed and billable receivables, and unbilled receivables. The Company’s receivables are primarily due from the U.S. government, or from prime contractors on which we are subcontractors and the end customer is the U.S. government, and are generally considered collectable from the perspective of the customer’s ability to pay. The Company does not have a material credit risk exposure. Unbilled receivables, substantially all of which are expected to be billed and collected within one year, are stated at their estimated realizable value and consist of costs and fees billable on contract completion or the occurrence of a specified event, other than the passage of time. Legal title to the related accumulated costs of contracts in progress generally vests with the U.S. government on the Company’s receipt of progress payments. Progress payments received of $28 million and $33 million offset unbilled receivables as of January 29, 2021 and January 31, 2020, respectively. Contract retentions are billed when contract conditions have been met and may relate to uncompleted indirect cost negotiations with the U.S. government. Based on historical experience, the majority of retention balances are expected to be collected beyond one year. Retention is presented in other assets on the consolidated balance sheets, see Note 3. Write-offs of retention balances have not been significant. Receivable balances are written-off in the period during which management determines they are uncollectable, and, at that time, such balances are removed from billed receivables and, if previously reserved, from the allowance.
Inventory	Inventory Inventory is substantially comprised of finished goods inventory purchased for resale to customers, such as tires and lubricants, and is valued at the lower of cost or net realizable value, generally using the average method. The Company evaluates current inventory against historical and planned usage to estimate the appropriate provision for obsolete inventory.
Business Combinations	Business Combinations The Company records all tangible and intangible assets acquired and liabilities assumed in a business combination at fair value as of the acquisition date, which is determined using a cost, market or income approach. The excess amount of the aggregated purchase consideration paid over the fair value of the net of assets acquired and liabilities assumed is recorded as goodwill. Acquisition date fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as measured on the acquisition date. The valuations are based on information that existed as of the acquisition date. During the measurement period that shall not exceed one year from the acquisition date, the Company may adjust provisional amounts recorded for assets acquired and liabilities assumed to reflect new information that the Company has subsequently obtained regarding facts and circumstances that existed as of the acquisition date. Acquisition and Integration Costs Acquisition-related costs that are not part of the purchase price consideration are generally expensed as incurred, except for certain costs that are deferred in connection with the issuance of debt. These costs typically include transaction-related costs, such as finder’s fees, legal, accounting and other professional costs. Integration-related costs typically include strategic consulting services, employee related costs, such as severance and accelerated vesting of assumed stock awards, costs to integrate information technology infrastructure, enterprise planning systems, processes, and other non-recurring integration-related costs. Acquisition and integration costs are presented together as acquisition and integration costs on the consolidated statements of income. The amounts recognized in acquisition and integration costs on the consolidated statements of income are as follows: Year Ended January 29, January 31, February 1, (in millions) Acquisition (1) $ 20 $ 2 $ 31 Integration (2)(3) 34 46 55 Total acquisition and integration costs $ 54 $ 48 $ 86 (1) Acquisition expenses recognized for the twelve months ended January 29, 2021, and January 31, 2020 are related to the acquisition of Unisys Federal. Acquisition expenses recognized for the twelve months ended February 1, 2019 are related to the acquisition of Engility. See Note 4 for additional information related to the acquisitions. (2) Integration expenses for the twelve months ended January 29, 2021, include an $11 million loss associated with the divestiture of non-strategic international operations. (3) Includes $6 million, $16 million, and $29 million of restructuring costs for the year ended January 29, 2021, January 31, 2020, and February 1, 2019, respectively, and $1 million and $5 million of impairment of right of use lease assets for fiscal 2021 and fiscal 2020, respectively. See Note 5 for additional information related to restructuring costs and impairments. Divestiture On July 3, 2020, in connection with the integration of Engility, the Company sold certain non-strategic international operations for $22 million and recognized a loss on the divestiture of $11 million, including $1 million of transaction costs. The loss is included in acquisition and integration costs on the consolidated statements of income. The Company has received $17 million in cash proceeds through January 29, 2021, with the remaining balance due in installments through October 2021.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired and liabilities assumed. Goodwill and indefinite-lived intangible assets are not amortized, but rather are tested for potential impairment annually at the beginning of the fourth quarter, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. There were no impairments during the periods presented. The goodwill impairment test is performed at the reporting unit level. The Company estimates and compares the fair value of each reporting unit to its respective carrying value including goodwill. The fair value of the Company’s reporting units are determined using either a market approach, income approach, or a combination of both, which involves the use of estimates and assumptions, including projected future operating results and cash flows, the cost of capital, and financial measures derived from observable market data of comparable public companies. If the fair value is less than the carrying value, the amount of impairment expense is equal to the difference between the reporting unit’s fair value and the reporting unit’s carrying value. Intangible assets with finite lives are amortized using the method that best reflects how their economic benefits are utilized or, if a pattern of economic benefits cannot be reliably determined, on a straight-line basis over their estimated useful lives. Intangible assets with finite lives are assessed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
Impairment of Long-lived Assets	Impairment of Long-lived Assets The Company evaluates its long-lived assets for potential impairment whenever there is evidence that events or changes in circumstances indicate that the carrying value may not be recoverable and the carrying amount of the asset exceeds its estimated future undiscounted cash flows. When the carrying amount of the asset exceeds its estimated future undiscounted cash flows, an impairment loss is recognized to reduce the asset’s carrying amount to its estimated fair value based on the present value of its estimated future cash flows.
Commitments and Contingencies	Commitments and Contingencies Accruals for commitments and loss contingencies are recorded when it is both probable that they will occur and the amounts can be reasonably estimated. In addition, legal fees are accrued for cases where a loss is probable and the related fees can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount of loss. The Company reviews these accruals quarterly and adjusts the accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other updated information.
Pension and Defined Benefit Plans	Pension and Defined Benefit Plans The Company measures plan assets and benefit obligations as of the month-end that is closest to its fiscal year-end. Accounting and reporting for the Company's pension and defined benefit plans requires the use of assumptions, including but not limited to, a discount rate and an expected return on assets. These assumptions are reviewed at least annually based on reviews of current plan information and consultation with the Company's independent actuary and the plans’ investment advisor. If these assumptions differ materially from actual results, the Company's obligations under the pension and defined benefit plans could also differ materially, potentially requiring the Company to record an additional liability. The Company's pension and defined benefit plan liabilities are developed from actuarial valuations, which are performed each year.
Marketable Securities, Policy	Investments in marketable securities consist of equity securities, which are recorded at fair value using observable inputs such as quoted prices in active markets (Level 1). As of January 29, 2021 and January 31, 2020, the fair value of our investments total $27 million and was included in other assets on the consolidated balance sheets. The Company's investments are primarily held in a custodial account, which includes investments to fund our deferred compensation plan liabilities.
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurement guidance prescribed by GAAP to value its financial instruments. The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than the quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). The carrying amounts of cash and cash equivalents, receivables, accounts payable and other amounts included in other current assets and current liabilities that meet the definition of a financial instrument approximate fair value because of the short-term nature of these amounts. The carrying value of the Company’s outstanding debt obligations approximates its fair value. The fair value of long-term debt is calculated using Level 2 inputs, based on interest rates available for debt with terms and maturities similar to the Company’s existing debt arrangements. Non-financial assets acquired and liabilities assumed in a business combination were measured at fair value using income, market and cost valuation methodologies. See Note 4. The fair value measurements were estimated using significant inputs that are not observable in the market and thus represent a Level 3 measurement.
Derivative Instruments Designated as Cash Flow Hedges	Derivative Instruments Designated as Cash Flow Hedges Derivative instruments are recorded on the consolidated balance sheets at fair value. Unrealized gains and losses on derivatives designated as cash flow hedges are reported in other comprehensive income (loss) and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions.
Lessee, Leases	The Company occupies most of its facilities under operating leases. Certain equipment also is leased under short-term or cancelable operating leases. Effective upon the adoption of ASU 2016-02, the Company recognizes a right of use (ROU) asset and a lease liability upon the commencement of its operating leases. The initial lease liability is equal to the future fixed minimum lease payments discounted using the Company’s incremental borrowing rate, on a secured basis. The lease term includes option renewal periods and early termination payments when it is reasonably certain that the Company will exercise those rights. The initial measurement of the ROU asset is equal to the initial lease liability plus any initial direct costs and prepayments, less any lease incentives. The Company recognizes lease costs on a straight-line basis over the remaining lease term, except for variable lease payments that are expensed in the period in which the obligation for those payments is incurred. For its facility leases, the Company combines and accounts for lease and non-lease components together as a single component. The Company does not recognize lease liabilities and ROU assets for facility leases with original terms of 12 months or less. ROU assets are evaluated for impairment as a long-lived asset.
Operating Cycle	Operating CycleThe Company’s operating cycle may be greater than one year and is measured by the average time intervening between the inception and the completion of contracts.
Research and Development	Research and Development The Company conducts research and development activities under customer-funded contracts and with company-funded independent research and development (IR&D) funds. IR&D efforts consist of projects involving basic research, applied research, development, and systems and other concept formulation studies. Company-funded IR&D expense is included in selling, general and administrative expenses (SG&A) and was $6 million, $7 million and $5 million in fiscal 2021, 2020 and 2019, respectively. Customer-funded research and development activities performed under customer contracts are charged directly to cost of revenues for those particular contracts.
Accounting Standards Updates	Accounting Standards Updates In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which requires entities to use a forward-looking model to estimate credit losses over the contractual term of financial assets, including short-term trade receivables and contract assets. The Company adopted ASU 2016-13 in the first quarter of fiscal 2021 using the modified retrospective approach. The adoption did not have a material impact on the Company’s financial statements. In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract , which aligns the capitalization requirements for implementation costs incurred in a hosting arrangement that is a service contract with the existing capitalization requirements for implementation costs incurred to develop or obtain internal-use software ( Subtopic 350-40 ). During the third quarter of fiscal 2020, the Company early adopted ASU 2018-15 and applied its provisions prospectively. The adoption did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases ( Topic 842 ), which supersedes the existing lease accounting standards ( Topic 840 ). The Company adopted the standard using the optional transition method. Accordingly, the prior periods were not recast, and all prior period amounts disclosed are presented under Accounting Standards Codification (ASC 840). As a result of the adoption of the new standard, on February 2, 2019, the Company recognized approximately $169 million of right of use operating assets and $184 million of operating lease liabilities, of which $140 million was noncurrent. The adoption did not have a material impact on retained earnings, the consolidated statements of income, or the consolidated statements of cash flows. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans , which modifies the disclosure requirements for the defined benefit pension plans and other postretirement plans. The Company early adopted the provisions of the standard in the fourth quarter of fiscal 2019, which did not result in a material impact to its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the revenue recognition requirements and some cost guidance included in the ASC. The Company adopted the standard on February 3, 2018, using the modified retrospective method. Under this method, the Company recognized the cumulative effect of adoption as an adjustment to its opening balance of retained earnings on February 3, 2018. Prior year periods were not retrospectively adjusted. The net impact to opening retained earnings as a result of the adoption was $3 million, attributable primarily to the change in accounting for programs previously accounted for using the efforts-expended method of percentage of completion. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedge Activities , which simplifies the application of hedge accounting and eliminates the requirement to separately measure and report hedge ineffectiveness. The Company early adopted the provisions of the standard in the first quarter of fiscal 2019. The adoption did not have a material impact on the Company's financial statements. Other Accounting Standards Updates effective after January 29, 2021 are not expected to have a material effect on the Company’s financial statements.
Revenue Recognition	Revenue Recognition The Company provides technical, engineering and enterprise IT services under long-term service arrangements primarily with the U.S. government including subcontracts with other contractors engaged in work for the U.S. government. The Company also serves a number of state and local governments, foreign governments and U.S. commercial customers. The Company provides services under various contract types, including firm-fixed price (FFP), time-and-materials (T&M), cost-plus-fixed-fee, cost-plus-award-fee and cost-plus-incentive-fee contracts. Our service arrangements typically involve an annual base period of performance followed by renewal periods that are accounted for as separate contracts upon each exercise. The Company recognizes revenue when, or as, we satisfy our performance obligations under a contract. A performance obligation is the unit of account for revenue recognition and refers to a promise in a contract to transfer a distinct service or good to the customer. The majority of the Company’s contracts contain a single performance obligation involving a significant integration of various activities that are performed together to deliver a combined service or solution. Performance obligations may be satisfied over time or at a point in time, but the majority of the Company’s performance obligations are satisfied over time. The Company selects the appropriate measure of progress for revenue recognition based on the nature of the performance obligation, contract type and other pertinent contract terms. Over time performance obligations may involve a series of recurring services, such as network operations and maintenance, operation and program support services, IT outsourcing services, and other IT arrangements where the Company is standing ready to provide support, when-and-if needed. Such performance obligations are satisfied over time because the customer simultaneously receives and consumes the benefits of our performance as services are provided. Alternatively, over time performance obligations may involve the completion of a contract deliverable. Examples include systems integration, network engineering, network design, and engineering and build services. Deliverable-based performance obligations are satisfied over time when the Company’s performance creates or enhances an asset that is controlled by the customer, or when the Company’s performance creates an asset that is customized to the customer’s specifications and the Company has a right to payment, including profit, for work performed to date. For recurring services performance obligations, the Company measures progress using either a cost input measure (cost-to-cost), a time-elapsed output measure, or the as-invoiced practical expedient. A cost input measure typically is applied to the Company’s cost-reimbursable contracts. Revenue is recognized based on the ratio of costs incurred to total estimated costs at completion. Award or incentive fees are allocated to the distinct periods to which they relate. For fixed-price contracts, a time-elapsed output measure is applied to fixed consideration, such that revenue is recognized ratably over the period of performance. Where fixed-price contracts also provide for reimbursement of certain costs, such as travel or other direct costs, consideration may be attributed only to a distinct subset of time within the performance period. The Company’s time-and-material and fixed price-level of effort contracts generally qualify for the as-invoiced practical expedient. Revenue is recognized in the amount to which the Company has a contractual right to invoice. Contract modifications typically create new enforceable rights and obligations, which are accounted for prospectively. Changes to our estimates of the transaction price are recognized as a cumulative adjustment to revenue. For deliverable-based performance obligations satisfied over time, the Company recognizes revenue using a cost input measure of progress (cost-to-cost), regardless of contract type. Revenue is recognized based on the ratio of costs incurred to total estimated costs at completion, except for certain contracts for which the costs associated with significant materials or hardware procurements are excluded from the measure of progress and revenue is recognized on an adjusted cost-to-cost basis. Contract modifications typically change currently enforceable rights and obligations and are accounted for as a cumulative adjustment to revenue. Changes to our estimates of transaction price are recognized as a cumulative adjustment to revenue. For performance obligations in which the Company does not transfer control over time, we recognize revenue at the point-in-time when the customer obtains control of the related asset, usually at the time of shipment or upon delivery. The Company accrues for shipping and handling costs occurring after the point-in-time control transfers to the customer. Recognizing revenue on long-term contracts involves significant estimates and judgments. The transaction price is the estimated amount of consideration we expect to receive for performance under our contracts. Contract terms may include variable consideration, such as reimbursable costs, award and incentive fees, usage-based fees, service-level penalties, performance bonuses, or other provisions that can either increase or decrease the transaction price. Variable amounts generally are determined upon our achievement of certain performance metrics, program milestones or cost targets and may be based upon customer discretion. When making our estimates, the Company considers the customer, contract terms, the complexity of the work and related risks, the extent of customer discretion, historical experience and the potential of a significant reversal of revenue. The Company includes variable consideration in the transaction price only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimating costs at completion is complex due to the nature of the services being performed and the length of certain contracts. Contract costs generally include direct costs, such as labor, subcontract costs and materials, and indirect costs identifiable with or allocable to a specific contract. Management must make assumptions regarding the complexity of the work to be performed, the schedule and associated tasks, labor productivity and availability, increases in wages and prices of materials, execution by our subcontractors, overhead cost rates, and other variables. Contract costs incurred for U.S. government contracts, including indirect costs, are subject to audit and adjustment by the Defense Contract Audit Agency ("DCAA"). Contract fulfillment costs are expensed as incurred except for certain costs incurred for transition, set-up or other fulfillment activities, which are capitalized and amortized on a straight-line basis over the expected period of benefit, which generally includes the base contract period of performance and anticipated renewal periods. The Company provides for anticipated losses on contracts with the U.S. government by recording an expense for the total expected loss during the period in which the losses are first determined. For contracts with multiple performance obligations, the Company allocates transaction price to each performance obligation based on the relative standalone selling price of each distinct performance obligation within the contract. Because the Company typically provides customized services and solutions that are specific to a single customer’s requirements, standalone selling price is most often estimated based on expected costs plus a reasonable profit margin.
Earnings Per Share (EPS)	Earnings per Share (EPS) Basic EPS is computed by dividing net income attributable to common stockholders by the basic weighted-average number of shares outstanding. Diluted EPS is computed similarly to basic EPS, except the weighted-average number of shares outstanding is increased to include the dilutive effect of outstanding stock options and other stock-based awards.
Property, Plant and Equipment	Property, plant, and equipment are carried at cost net of accumulated depreciation and amortization. Purchases of property, plant, and equipment, as well as costs associated with major renewals and betterments, are capitalized. Maintenance, repairs and minor renewals and betterments are expensed as incurred. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts and any resulting gain or loss is recognized.
